"For this very reason, make every effort to add to your faith goodness..." (2 Pet. 1:1-9).
From Mark Buchanan's book, "Hidden in Plain Sight":
"Out of goodness, God acts. Who God is precedes what God does. His actions derive from His behavior."
So the call to add to your faith goodness is:
"More than a call to probity and decency and regular hygiene. It is nothing less than an invitation to enter and experience and imitate the very personhood of God...Its exhausting to keep building the edifice of good behavior on a foundation of sticks."
One practical suggestion he gives in the pursuit of adding goodness to your faith is to become a true worshipper. Start at this point, and then "doing" good will naturally follow "being" good, and "being" good comes only by "His divine power" (2 Pet. 1:3)
